THlLL-COUPLING.

` SPECIFICATION forming part of Letters Patent No. 279,381, dated June 12, 1883. Application filed April 30, 18H3. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. HAsKELL, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in 'Phill-Couplings, of which the following is a speciiication.

My invention relates to improvements in thill-couplings of the same general character as those shown in my prior Patents No. 185,528, December 19, 1876, and No. 205,082, June 18, 1878, the present improvements comprising certain details in the construction of the coupling with the view of simplifying the construction of the same and increasing its efficiency.

In the accompanying drawings, Figure 1 is a side view of my improved thill-coupling, the axle being in section; Fig. 2,- a longitudinal section ofthe coupling, Figiv 3, a perspective view of the parts of the same detached from each other; Fig. 4, a sectional plan view on v the line 1 2, Fig. 1; ,Fig. 5, a transverse section on the line 3 4, Fig. 2; and Fig. 6, a detached view of one form of pivot-bolt.

A represents the axle of the vehicle, and B j one of the shafts or the pole of the same, to which is secured the usual thill-iron, D, having'an eye, c.

To the axle is secured the usual clip, E, having ears b b, in which are openings for the reception ofthe pivot-pin d, wh ich passes through the eye c of -the thill-iron, the latter fitting snugly between the ears b of the clip, as shown in Fig. 4. A block, F, is also fitted between the ears Z), and is supported in position vertically by means of lugs e e, resting on said ears, the block being recessed for the reception of the eye a', against which it bears at andV near each end, as shown in Fig. 4. The block F projects below the ears I), and to this projecting portion of the block is hung on each side a lever, G, the upper or' long arms of these levers being notched for adaptation to `the grooved projecting ends ofthe pivot-pin d, so that when the levers are in the position shown in Figfl the lateral removal or displacement of said pin or spreading of the ears b yis impossible.

In the projecting lower portion of the block F4 are formed grooves f, for the reception of ribs g on a box, J, which is open at the rear end, and contains a spring adapted to bear upon -one of the nuts h, whereby the clip is secured, the front end of the spring being acted upon by a nut, m,which is adapted to a screwstem, n, swiveled to the front end of the box, the nut being guided in thebox and prevented from turning by means of a lug, s, adapted to a groove, t, in the bottom of the box. Figs. 2 and 5.) Any desiredform of lug or bearing for the spring may be used in place of the nut 11.; but the latter is convenient, and

-its use is therefore preferred. The box J is further guided in the block F by means of projections p, which bear upon the under side of similar projections, q, on the block, and on each of said projections p is a lug, 1o, adapted t0 bear upon the short'arm of one of the levers G, as shown in Fig. 1.

In fitting the coupling together the block F and the parts carried thereby are iirst applied to the clip, the screw-stein n being loosenedand the levers G retracted, as shown by dotted lines in Fig. 1. The thill is then applied and the pin d inserted, after which the notched arms of the levers G are appliedto the grooved ends of the pin d, and the screw-stein n is turned so as to compress the spring and cause the box J to be thrust forward. The lugs w are thus brought into contact with the short arms ofthe levers G, and the disengagement ofthe notched long arms ofsaid levers from the grooved ends ofthe pin d is prevented, further movement 0f the box J being then transmitted to the block F, which is caused to bear upon the eye c of the thill-iron with any desired amount ofpressure, and thus effectually prevent any rattling of said thill.

The pin. d mayhave the portion m, which is adapted to the opening in one of the ears b, square, as shown in Fig. 4, orbeveled, as shown in Fig. 6, so as to insure the adjustment ofthe pin to its proper lateral position. f

(see

By adapting the sliding box J to guides` in l IOO box J in this case being secured to the block F, or adapted to'bear against lugson the same, so that on tightening the screw-stem a the block Will be caused to bear firmly against the eye a.

Instead of a coiled spring, ablock of vrubber or other elastic material may be used; but the coiled spring is preferred.

I claim as my inventiond 1. The combination of the clip, thill-iron, and pivot-pin, having grooved ends, with the bearing-block F, and the notched retaininglevers G G, hung to the block and adapted to the opposite grooved ends of the pin, as set forth.

2. The combination of the thill-eye and pivot-pin With the block F, the Sliding box J,

the sliding box .J and its lugs w, the-spring M, andthe bearing h, as set forth.

5. The combination ofthe thill-eye and piv- 0t-pin, the block F and its notched levers G, the sliding box J`, having lugs w, the spring M, the adjusting-screw a, and the bearing zf, as set forth. l I

6. The combination of the block 'F,'the sliding box J, the spring M, the nut m, and the screw-stem n, swiveled to the box and adapted to the nut, as set forth.

7. The combination of the block F, the sliding boxv J', having a groove, t, the spring M, the nut m, vhaving a lug, s, and the screw-stem n, as set forth. Y'

In testimony whereof l have signed my name to this specification in the presence of two sub- 4o scribing Witnesses.

GEORGE "W, HASKELL.
